                             UNCONDITIONAL GUARANTY

FOR VALUE RECEIVED, and in order to induce MERRILL LYNCH BUSINESS FINANCIAL
SERVICES INC. ("MLBFS") to advance moneys or extend or continue to extend credit
or lease property to or for the benefit of, or modify its credit relationship
with, or enter into any other financial accommodations with ASPECT SYSTEMS, INC.
F/K/A ASPECT SEMIQUIP INTERNATIONAL, INC., a corporation organized and existing
under the laws of the State of Arizona (with any successor in interest,
including, without limitation, any successor by merger or by operation of law,
herein collectively referred to as "Customer") under (a) that certain TERM LOAN
AND SECURITY AGREEMENT DATED AS OF MAY 14, 2004 between MLBFS and Customer (the
"Loan Agreement"), (b) any "Loan Documents", as that term is defined in the Loan
Agreement, including, without limitation, the NOTE(S) incorporated by reference
in the Loan Agreement, and (c) all present and future amendments, restatements,
supplements and other evidences of any extensions, increases, renewals,
modifications and other changes of or to the Loan Agreement or any Loan
Documents (collectively, the "Guaranteed Documents"), and for other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the undersigned, DND TECHNOLOGIES, INC., a corporation organized
and existing under the laws of the State of Nevada ("Guarantor"), hereby
unconditionally guarantees to MLBFS: (i) the prompt and full payment when due,
by acceleration or otherwise, of all sums now or any time hereafter due from
Customer to MLBFS under the Guaranteed Documents, (ii) the prompt, full and
faithful performance and discharge by Customer of each and every other covenant
and warranty of Customer set forth in the Guaranteed Documents, and (iii) the
prompt and full payment and performance of all other indebtedness, liabilities
and obligations of Customer to MLBFS, howsoever created or evidenced, and
whether now existing or hereafter arising (collectively, the "Obligations").
Guarantor further agrees to pay all reasonable costs and expenses (including,
but not limited to, court costs and reasonable attorneys' fees) paid or incurred
by MLBFS in endeavoring to collect or enforce performance of any of the
Obligations, or in enforcing this Guaranty. Guarantor acknowledges that MLBFS is
relying on the execution and delivery of this Guaranty in advancing moneys to or
extending or continuing to extend credit to or for the benefit of Customer.

This Guaranty is absolute, unconditional and continuing and shall remain in
effect until all of the Obligations shall have been fully and indefeasibly paid,
performed and discharged. Upon the occurrence and during the continuance of any
default or Event of Default under any of the Guaranteed Documents, any or all of
the indebtedness hereby guaranteed then existing shall, at the option of MLBFS,
become immediately due and payable from Guarantor (it being understood, however,
that upon the occurrence of any "Bankruptcy Event", as defined in the Loan
Agreement, all such indebtedness shall automatically become due and payable
without action on the part of MLBFS. Notwithstanding the occurrence of any such
event, this Guaranty shall continue and remain in full force and effect. To the
extent MLBFS receives payment with respect to the Obligations, and all or any
part of such payment is subsequently invalidated, declared to be fraudulent or
preferential, set aside, required to be repaid by MLBFS or is repaid by MLBFS
pursuant to a settlement agreement, to a trustee, receiver or any other person
or entity, whether under any Bankruptcy law or otherwise (a "Returned Payment"),
this Guaranty shall continue to be effective or shall be reinstated, as the case
may be, to the extent of such payment or repayment by MLBFS, and the
indebtedness or part thereof intended to be satisfied by such Returned Payment
shall be revived and continued in full force and effect as if said Returned
Payment had not been made.

The liability of Guarantor hereunder shall in no event be affected or impaired
by any of the following, any of which may be done or omitted by MLBFS from time
to time, without notice to or the consent of Guarantor: (a) any renewals,
amendments, restatements, modifications or supplements of or to any of the
Guaranteed Documents, or any extensions, forbearances, compromises or releases
of any of the Obligations or any of MLBFS' rights under any of the Guaranteed
Documents; (b) any acceptance by

<PAGE>

MLBFS of any collateral or security for, or other guarantees of, any of the
Obligations; (c) any failure, neglect or omission on the part of MLBFS to
realize upon or protect any of the Obligations, or any collateral or security
therefor, or to exercise any lien upon or right of appropriation of any moneys,
credits or property of Customer or any other guarantor, possessed by or under
the control of MLBFS or any of its affiliates, toward the liquidation or
reduction of the Obligations; (d) any invalidity, irregularity or
unenforceability of all or any part of the Obligations, of any collateral
security for the Obligations, or the Guaranteed Documents; (e) any application
of payments or credits by MLBFS; (f) the granting of credit from time to time by
MLBFS to Customer in excess of the amount set forth in the Guaranteed Documents;
or (g) any other act of commission or omission of any kind or at any time upon
the part of MLBFS or any of its affiliates or any of their respective employees
or agents with respect to any matter whatsoever. MLBFS shall not to required at
any time, as a condition of Guarantor's obligations hereunder, to resort to
payment from Customer or other persons or entities whatsoever, or any of their
properties or estates, or resort to any collateral or pursue or exhaust any
other rights or remedies whatsoever.

No release or discharge in whole or in part of any other guarantor of the
Obligations shall release or discharge Guarantor unless and until all of the
Obligations shall have been indefeasibly fully paid and discharged. Guarantor
expressly waives presentment, protest, demand, notice of dishonor or default,
notice of acceptance of this Guaranty, notice of advancement of funds under the
Guaranteed Documents and all other notices and formalities to which Customer or
Guarantor might be entitled, by statute or otherwise, and, so long as there are
any Obligations or MLBFS is committed to extend credit to Customer, waives any
right to revoke or terminate this Guaranty without the express written consent
of MLBFS.

So long as there are any Obligations, Guarantor shall not have any clam, remedy
or right of subrogation, reimbursement, exoneration, contribution,
indemnification, or participation in any claim, right, or remedy of MLBFS
against Customer or any security which MLBFS now has or hereafter acquires,
whether or not such claim, right or remedy arises in equity, under contract, by
statute, under common law, or otherwise.

MLBFS is hereby irrevocably authorized by Guarantor at any time during the
continuance of an Event of Default under the Loan Agreement or any other of the
Guaranteed Documents or in respect of any of the Obligations, in its sole
discretion and without demand or notice of any kind, to appropriate, hold, set
off and apply toward the payment of any amount due hereunder, in such order of
application as MLBFS may elect, all cash, credits, deposits, accounts, financial
assets, investment property, securities and any other property of Guarantor
which is in transit to or in the possession, custody or control of MLBFS or
Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), or any of their
respective agents, bailees or affiliates. Guarantor hereby collaterally assigns
and grants to MLBFS a continuing security interest in all such property as
additional security for the Obligations. Upon the occurrence and during the
continuance of an Event of Default, MLBFS shall have all rights in such property
available to collateral assignees and secured parties under all applicable laws,
including, without limitation, the Uniform Commercial Code.

Guarantor agrees to furnish to MLBFS such financial information concerning
Guarantor as may be required by any of the Guaranteed Documents or as MLBFS may
otherwise from time to time reasonably request. Guarantor further hereby
irrevocably authorizes MLBFS and each of its affiliates, including without
limitation MLPF&S, to at any time (whether or not an Event of Default shall have
occurred) obtain from and disclose to each other any and all financial and other
information about Guarantor.

No delay on the part of MLBFS in the exercise of any right or remedy under any
of the Guaranteed Documents, this Guaranty or any other agreement shall operate
as a waiver thereof, and, without limiting the foregoing, no delay in the
enforcement of any security interest, and no single or partial exercise by MLBFS
of any right or remedy shall preclude any other or further exercise thereof or
the exercise of any


                                       2

other right or remedy. This Guaranty may be executed in any number of
counterparts, each of which counterparts, once they are executed and delivered,
shall be deemed to be an original and all of which counterparts, taken together,
shall constitute but one and the same Guaranty. This Guaranty shall be binding
upon Guarantor and its successors and assigns, and shall inure to the benefit of
MLBFS and its successors and assigns. If there is more than one guarantor of the
Obligations, all of the obligations and agreements of Guarantor are joint and
several with such other guarantors.

This Guaranty shall be governed by the laws of the State of Illinois, WITHOUT
LIMITING THE RIGHT OF MLBFS TO ENFORCE THIS GUARANTY IN ANY JURISDICTION AND
VENUE PERMITTED BY APPLICABLE LAW: (I) GUARANTOR AGREES THAT THIS GUARANTY MAY
AT THE OPTION OF MLBFS BE ENFORCED BY MLBFS IN EITHER THE STATE OF ILLINOIS OR
IN ANY OTHER JURISDICTION WHERE GUARANTOR, CUSTOMER OR ANY COLLATERAL FOR THE
OBLIGATIONS OF CUSTOMER MAY BE LOCATED, (II) GUARANTOR IRREVOCABLY SUBMITS
ITSELF TO JURISDICTION IN THE STATE OF ILLINOIS AND VENUE IN ANY STATE OR
FEDERAL COURT IN THE COUNTY OF COOK FOR SUCH PURPOSES AND (III) GUARANTOR WAIVES
ANY AND ALL RIGHTS TO CONTEST SAID JURISDICTION AND VENUE AND THE CONVENIENCE OF
ANY SUCH FORUM AND ANY AND ALL RIGHTS TO REMOVE SUCH ACTION FROM STATE TO
FEDERAL COURT. GUARANTOR FURTHER WAIVES ANY RIGHTS TO COMMENCE ANY ACTION
AGAINST MLBFS IN ANY JURISDICTION EXCEPT IN THE COUNTY OF COOK AND STATE OF
ILLINOIS. MLBFS AND GUARANTOR HEREBY EACH EXPRESSLY WAIVE ANY AND ALL RIGHTS TO
A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF
THE PARTIES AGAINST THE OTHER PARTY WITH RESPECT TO ANY MATTER RELATING TO,
ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS GUARANTY AND/OR ANY OF THE
TRANSACTIONS WHICH ARE THE SUBJECT MATTER OF THIS GUARANTY. GUARANTOR FURTHER
WAIVES THE RIGHT TO BRING ANY NON-COMPULSORY COUNTERCLAIMS. Wherever possible
each provision of this Guaranty shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of this Guaranty
shall be prohibited by or invalid under such law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Guaranty. No modification or waiver of any of the provisions of this Guaranty
shall be effective unless in writing and signed by both Guarantor and an officer
of MLBFS. Each signatory on behalf of Guarantor warrants that he or she has
authority to sign on behalf of Guarantor, and by so signing, to bind Guarantor
hereunder.
